T 0 all whom it may concern:

Be it known that I, VICTOR CmiMrEU, a citizen of the Republic of France, and residing at Paris, Seine Department, No.- 54

Faubourg Saint-Honor, in the Republic .of'

France, have invented certain new and useful Improvements in Methods of Cooling Liquids and Charging the Same with Gas by the Use of Snowlike Carbonic Anhydride (for which I have filed applications in France, Oct. 22 and Nov. 28, 1919), of which the following is a specification.

This invention relates to a method for simultaneously cooling and charging any suitable liquid with gas, and more particularly a drink. The method consists in principle in maintaining within said liquid and in contact therewith a suitable quantity of "snow-like carbonic anhydride until the liquid is properly cooled and chargedwith gas. This invention also relates to an apparatus permitting the maintenance in said liquid of the proper amount of snow-like v carbonic anhydride used for cooling and for charging with gas.

A device of this nature pfinsists for instance of a perforated bell-shaped member provided with a. handle whereby said member may be inserted into the mass of snowlike carbonic anhydride for thepurpose of filling the same with this substance.

This invention consists in forming around the mass of snow-like substance to be placed in the liquid a film of ice whereby the disengagement of gas is prevented from taking place in a turbulent manner and at an unduly rapid rate.

The entire device consisting of a perforated bell-shaped or like member, snowlike carbonic anhydride disposed therein and an outer film of ice, thus constitutes a new product which. may be employed in a weight of ice, and if thereof a mas of such snow-like substance is maintained at the bottom of a glass of Water, for instance, carbonic acid will be produced for charging the water',,together with a. considerable cooling efiect.

For instance eight grammes of said snowlike substance will introduce into water 1200 frlgories'and 4 liters of gas, which is suffi- 'cient for the charging of an average sized Fig. 1 is an elevation of the structional form.

Fig. 2 shows the second constructional form partly in elevation and partly in section. 7 l

This device consists of a small bell-shaped ".member 1 (Fig. 1) provided with a handle 2 and having therein the small apertures or narrow slots 3 in considerable number, through which the carbonic acid gas is given off asthe snow-like substance melts, the device being more particularly adapted for the cooling of drinks. But it has been remarked that in spite of the precautions which may be taken and the form adopted, the gas is given off in a turbulent manner and in large bubbles, whence it results that the liquid is imperfectly charged with gas. On the other hand, when the fusion of the snow-like block is already in the advanced stage, small particles of the substance become detached fromivith a film of ice. For this purpose covered "with a uniform layer of ioe'through Which-the gas is nowfgiven off only in the shape of 'finebub'bles.

lengthof time in the previously cooled liq- ;uid, the regulating layer of ice may reach several millimeters thickness.

which is placed in a glass containinga drink If the bell-shaped member is allowed to remain for a sufiicient" its" will exert a double action by charging the liquidlwi'th' gas and by cooling the same. It

is of course understood that said bell-shaped members IHQbQ'CODStIHGtQd in ny suits/bk thin stamped metal, the rim of whichis set manner and may be given the most varied forms. In the preferred construction, the .bellshaped members and the handle thereof may be manufactured by the lathe turning process-from a piece of light-wood, thus obtain ing a very lnexpensive device, and each consumer may destroy the bell-shaped member after use in the same manner as for a piece of straw employed for drinking purpose.

The dimensions of the device are calculated in such manner that said member is an excess of pressure caused by the resistance wh1ch the outer covering affords to thedisengagement of carbonic acid gas, and

to" obviate the breakage of the bell shaped member under the eilect of an excessive internal pressure.

A considerable number of such devices covered; with ice by the hereinbefore described method may be prepared in advance and preserved in heat protecting receptacles such as Dewar vessels forthe space' of several'days, and they will afl'ord a substitute fora soda water supply bottle and for ice.

iA'ccord ing to the .secondconstructional 'form (Fig. 2) the apparatus consists of a metallic bell-shapgd member provided with a handle." The; 115 is'made of stamped metal; and is closed by a'cover 6 made of in a bezel and engages a circular groove 7 provided above the edge of the bell; The handle 8 may be fixed at the top of the bell in a suitable manner, 1

When the apparatus, filled with carbonic anhydride, is immersed in a liquid, the gas a set free by evaporation of the carbonic anhydride escapes in form -of fine bubbles through the circularinterstices which remains between the cover and the edge of the bell.

It is of course understood that the use of such devices is not limitedto their application to drinks, and by/suitably varying the size and shape of the bell-shaped members, these latter may be made the subject of industrial applications i'n the preparation of alimentary products.

Claims- 1. A method for simultaneously cooling 7 and charging a liquid with gas, consisting in maintainlng within said liquid and in contact therewith a suitable quantity of snow-like carbonic anhydride.

2. In a method for simultaneously cooling and charging liquids with gas, the immer sion of a measured quantity of snow-like carbonic anhydride in-those liquids previously brought to a temperature near the point of solidification thereof, saidimmersion having for its object the formation of .a film of ice surrounding said quantity of snow-like I substance whereby the disengagement of carbonic acid-gas shall be moderated.

In testimony that claim theforegoing as my invention I have signed my name in presence'of a'subscribing witness.
